This is the story of Rysdyk 's Big Bull or Hambletonian, the Father of the American Standardbred Trotting Horse Breed in American. Hambletonian was a foal of a old Butcher's nag, but his handler, Rysdyk, knew that he was fast and valuable and worked very hard to buy him and his mother. Hambletonian proved to be one of the fastest trotting horses in American and over 60% of modern Standardbreds can claim a link to Hambletonian. This is his story.
